docs: Mention G_ENABLE_DIAGNOSTIC in the porting notes

Since part of our type system is resolved at run time, we need to use
run time facilities to get diagnostic messages, like deprecation
warnings for properties and signals.

We should mention the G_ENABLE_DIAGNOSTIC environment variable in the
migration guide, to let developers know how to catch deprecations and
changes while porting their code.
